To all whom it may concern;

Be it known that I, JOHN RYAN, a subject of the King of Great Britain,residing at Winnipeg, in the Province of Manitoba and Dominion ofCanada, have invented new and useful Improvements in Twisting-Machines,of which the following is a specification.

This invention relates to machines or de- Vices for twisting yarnpreparatory to reeling the same to form skeins, and it has for itsobject to produce a simple and eflicient device whereby two or morethreads may be easily and expeditiously twisted to form a yarn.

A further object of the invention is to provide a simple and efficientstop motion whereby in the event of the breaking or running out of anyone of the threads the twisting device may be stopped.

A still further object of the invention is to produce a simple andeflicient twisting device which may be run at high speed without dangerof undue vibration.

A still further object of the invention is to produce a simple andeflicient twisting device the shaft of which as well as one of the shaftbearings shall be slotted for the insertion of the threads required toform the am. y With these and other ends in view which will readilyappear as the nature of the invention is better understood, the sameconsists in the improved construction and novel arrangement andcombination of parts which will be hereinafter fully described andparticularly pointed out in the claims.

In the accompanying drawings has been illustrated a simple and preferredform of the invention, it being, however, understood that no limitationis necessarily made to the precise structural details therein exhibited,but that changes, alterations and modifications within the scope of theclaims may be resorted to when desired.

In the drawings,Figure 1 is a View in front elevation showing a singleunit of the improved twisting device and a portion of the supportingframe for the same, Fig. 2 is a sectional View taken on thejline 22 inFig. 1. Fig. 3 is a sectional view taken on the line 33 in Fig. 1. Fig.4 is a sectional view taken on the line 44 in Fig. 1. Fig. 5 is asectional view taken on the line 55 in Fig. 1. Fig. 6 is a sectionaldetail view 1 front elevation diagrammatically showing a plurality ofunits of the improved twisting device and related parts. Fig. 8. is averti= cal sectional view taken on the line 88 in Fig. 1.

The frame A of the improved device may be of suitable dimensions toaccommodate any desired number of units or twisting devices, and saidframe comprises in its construction a bench including front and rearmembers 1, 1* a foot piece 2 and a cap piece 3, said members beingusually sustained in parallel relation by uprights, one of which isshown at 4.

Each unit of the improved twisting device comprises a shaft 5 whichextends vertically through the bench 1 and the lower end of which isstepped in the foot piece 2. Each of the shafts 5 is provided at itsupper end with a fru'sto-conical.enlargement 6 having a bore or recess 7and a slot 8 which communicates with said bore or recess.

The cap plece 3 has a recess 9 constituting ,a bearing for thefrusto-conical portion 6,

said bearing being formed adjacent to the front edge of the cap piece;the slot or aperture 10 at the front of the recess 9 may when desired bebrought into registry with the slot 8 of the shaft. Each shaft 5 carriesa disk or table 11 upon which any desired number of spindles 12 areequidistantly disposed to support the spools or bobbins 13 holding thethread which is to be twisted. In the drawing three bobbin holdingspindles have been shown, but any desired number from two upward may beused.

Pivotally connected with the shaft 5 adjacent to the upper face of thedisk or table 1 is a plurality of levers 14, one of which extendsradially from the shaft adjacent to each bobbin carrying spindle. Eachlever 14 is provided with an upwardly extending arm 15 havingan eye 16.The shaft 5 is also provided at a suitable distance from the upper endwith a plurality of radially disposed arms 17 the number of whichcorresponds to that of the levers 14, said arms being provided adjacentto their outer ends with eyes 18. Pivotally mounted upon the rear member1 of the bench adjacent to and in rear of the shaft 5 is an arm or lever19 which may be guided through a keeper 20 upon the front member 1 ofthe bench. Pivotally connected with said lever is a finger 21 which whenplaced in an upright in Fig. 1, is adapted to engage a notch 23 in aslide 24 which is movably supported in keepers 25 upon the front edge ofthe bench 1. To this slide reciprocatory motion is imparted when themachine is in operation by any suitable means, such as a cam wheel 26 onthe line shaft 27, said cam wheel being provided with a zigzag groove 28engaging an arm 2-9 connected with the slide 24, which latter will thusbe constantly reciprocated when the line shaft is in motion.

The shaft 5 of each unit is provided with a grooved pulley 30 connectedby a quarter-- twisted band 31 with a grooved pulley 32 which is looselymounted upon the line shaft, said grooved pulley 32 being provided witha clutch member 33 adapted to be engaged by a slidable clutch member 34which is feathered or, keyed upon the line shaft. The slidable clutchmember 34 is eng'aged by a bifurcated arm 35 associated with the arm orlever 19 which constitutes a shipping lever, a suitably arranged spring36 being provided whereby the clutch member 34 will be normally held inengagement with the clutch member 33 of the loose pul- In connectionwith this device, reeling mechanism of any ordinary well knownconstruction may be employed for the purpose of reeling or skeining theyarn as it comes from the twisting device. Such reeling mechanism may bedriven in any convenient manner from the shaft 5 so that it will bestopped or started concurrently with the stoppage and the starting ofthe twisting mechanism.

From the foregoing description, taken in connection with the drawingshereto annexed, the operation and advantages of this invention will bereadily understood by those skilled in the art to which it appertains.The thread coming from each cop or bobbin is threaded through the eye 18of an arm 17 and through the eye 16 of the arm 15 assothe shaft may beprovided with as many slots 8 communicating with the bore as there arethreads to be twisted, although this is not deemed absolutely essential.As the twisted yarn issues from the bore of the shaft it passes to thereeling device, whereby it is reeled to form skeins, as is wellunderstood. In the event of the breakage or running out of any onethread the lever 14, which has been sustained in an elevated position bysuch thread, will drop by gravity and will presently engage the finger21 of the arm or lever 19, tilting such finger to theposition indicatedin dotted lines in Fig. 1, and causing it to engage a notch 23 of thereciprocating slide 24. The shipping lever will thereby be moved in thedirection and out of engagement with the clutch member 33 associatedwith the loose pulley 34. The latter thus becomes idle upon the lineshaft, and motion of the twisting unit and associated parts will thus beinstantly stopped. To start the unit, the operator merely releases theshipping lever 19 fromthe spring catch 37 and restores the finger 21 toan upright position where it is retained by the lateral projection 22.This may bedone while the lever 19 is held by the handle 21, and saidlever is then moved in the proper direction to replace the clutch member34 in engagement with the clutch member 33 where it will be safelyretained by the action of the spring 36. It will thus be seen that eachunit of the machine may be stopped automatically by the running out orbreaking of a single thread and may be again started in motion withoutaffecting the operation of the remaining units of the'maand of thebearing enable the threads to be conveniently and quickly inserted sothat interruptions caused. by broken threads or from other causes willbe of the shortest possible duration.

Having thus described the invention, what is claimed as new, is

1. In a twisting device, a twisting unit including a verticallysupported shaft, a disk on said shaft having a plurality of upstandingspool carrying spindles, levers extending radially from the shaft andhaving arms provided with guide eyes, arms eX- tending radially from theshaft and having guide eyes, a line shaft, means for transmitting motionfrom the line shaft to the vertical shaft including a loose pulleyhaving a clutch member and a slidable clutch feathered upon the lineshaft, a shipping lever having a bifurcated arm engaging the slidableclutch member, said shipping lever being provided with a finger having alateral extension whereby it may be supported in an upright position inthe path of the levers extending radially from the vertical shaft whenthe said levers lie flat upon the disk, and a reciprocatory slide havinga notch adapted to engage the finger when the latter is tilted.
